(Cl. 20-49) V 14 Claims.

This invention relates to a mechanism for mounting a window in a frame and is so constructed that the window may be adjusted as a double hung sliding window and yet may be safely tilted away from its normal vertical position for washing, room ventilation or like purpose.

One of the objects of the invention is to provide a vertically movable window with devices adapting the window for tilting movement on a horizontal axis and for locking the window against vertical movement when in tilted position.

A further object is to provide checking devices for the window, coacting and coordinated with the tilting and locking mechanism in such manner that a single set of control bars or strips on the window frame serves as the stationary checking and locking elements of the assembly, thereby facilitating the installation of the window and assuring the unfailing operation thereof in use.

It is a further object to provide, in a window mounting of this type, against the entrance of air ormoisture into or through the window mounting.

These and other objects will appear more fully from the following description, when considered in connection with the drawings in which;

Referring to Figs. 1 to 4, there is illustrated a window frame 2 formed with side channels 3 in which the upper and lower windows t and 6 are slidably mounted. Each window is provided at each side edge with a supporting member 8, particularly illustrated in Figs. 4-10. The supporting members are mounted permanently in the side channels or guides of the frame so that their only movement is up and down in the channels. The windows are hingedly connected to the supporting members by devices to be presently described.

Referring now to Fig. 4, it will be noted that the side edges of the window are of reduced width, the supporting members 8 constituting extensions of the sides of the window when the latter is in vertical position. The windows 13 and 6 and supporting members 8 are hingedly connected as at H! and are formed with similarly shaped contacting faces, preferably of cylindrical or other out-of-round configuration, so that on tilting the window the supporting members are forced outwardly, away from the window, the tendency being normally to retain the window and supporting members in vertical alinement.

It is preferred to face the window and supporting members with metal where these members contact. As shown, the window supports 8 are formed entirely of metal, although, as will be understood, these supports may be formed of wood or other material. In the embodiment shown, each edge of each window is provided with an edge channel or facing formed with an arcuate portion extending across the outer edge of the window and with side flanges embracing the window to reinforce and strengthen the window and to retain the facing securely in place. The facing for the window edge and the supporting member may be formed with one or more cooperating ribs and depressions l4, two being illustrated at each edge of each window, to more tightly close the space between the window and its supports when the window is in its normal vertical position.

It will be understood that there may be sub stituted for the ribs and depressions l4 9. flexible sealing strip [4a as illustrated in Fig. 5a.

The devices for supporting and controlling the window and its movements in the frame are particularly arranged so that one pair of control bars or strips I6 can be utilized for every function of the window, that is, the mounting as well as the control of its movements. The strips 16 extend through the major portions of the guide channels 3 of the window frames 2. The strips are secured at their ends, preferably by a reverse bent attachment element l8 to space the strips from the frame. Elements I8 are secured as at H] to the inner face of the window frame and at 2 to the ends of the strips IS. The strips l6 are preferably formed of non-corrosive metal, for example, brass, and are formed with a succession of small, closely spaced apertures 22 for receiving the locking elements of the window control. The apertures 22 in the strips are placed sufiiciently close together that where the window is stopped at a point such that the pins 36 engage between the apertures therein, an upward movement of one side of the window and a downward movement of the other side will still securely lock the window and prevent it from falling out of the frame. The window can then be tilted to its normal vertical position thereafter, even though the pins on opposite sides of the window were not in corresponding holes in their respective strips. The openings in strips I6 for receiving attachment screws are preferably in the form of transverse slots 20a. (Fig. 17), to permit centering of the strip.

Each of the supporting members 8 of each window is formed with hinging devices indicated generally at 10, checking devices indicated generally at 24, and spacing or skid devices 26. 1

These elements may be independently secured to the support 8, but it is preferred to construct each so that it will pass into the channel constituting the support 8 and beneath the flanges thereon, to be held against lateral displacement. The various elements constituting the control devices for the window may then be linked together so that, on securement of the central hinge elements to the channel, all of the parts will be held inor two locking pins 36 (two being shown) constructed to engage in the openings 22 in the control strip when the collar is in extended position. The collar is formed with end extensions 38 fitted in guide slots 40 of the block 42 when the parts are assembled. The block 42 is constructed to be permanently and immovably mounted in the supporting member 8, being held immovably against the said supporting member by engagement therewith of a shoulder forming the cylindrical portion 29 of the attachment pin 28, and being further locked against movement .by projections 44 extending through openings formed in the support 8. A spring 46 is mounted in the base of the block 42 and exerts pressure on the collar 32 to force it outwardly when the cams 36 and 34 permit. The base of the pin 28 is screwthreaded for receiving an attachment screw 48 for connecting the hinge pin 28 to a block 50 permanently mounted on the window sash. The block 50 has a base portion 52 whereby it is secured to the window, and a hollow cylindrical projection 54 for receiving a spring 56 and collar 58, the position of the latter being controlled by adjustment of the screw 48.

The reduced extension 3| of the hinge pin 28 is formed with fiat surfaces or other out-of-round configuration corresponding with that of the central opening of block 56. The pin 28 will there- I fore be turned with the window 4, thus turning the cam surfaces 36 away from contact with the cams 34 to permit the collar 32 to be moved outwardly into locking position, through the force of the spring 45, when the window is turned away from vertical position. The parts are held assembled with the supporting members 8 pressed firmly against the window 4 or B, through the force of the relatively stronger springs 56.

It has been found unnecessary to supply Window weights for most household windows where checking devices of the type herein disclosed are employed. The checking devices as herein disclosed comprise a housing 66 formed with a ho1- low interior recess 62 for receiving the cam member 64. This cam member is preferably formed as an open U-shaped spring member, with the bend of the U at the base, and with the upper free edge inclined outwardly toward the supporting member H5. A roller 66 engages with cam member 64 and control strip l6, so that, as the window is lowered, the roller moves up the inclined surface of the cam, with the result that the friction between the roller and the strip l6 opposes downward movement of the window. On upward movement of the window the roller moves to inoperative or non-checking position. The housing is formed with extensions 68 embracing the control strip I6, so that the position of the strip with respect to the checking devices and locking devices is made certain. The ends of the housings 6B are cut away as at T6 for receiving the anchoring links 12 secured to the block 42 for positioning the checking devices with respect to the hinging assembly.

The resilient spacing members 26 may be of general arch formation, with the end extensions M and 15 shaped generally to fit the interior of the supporting member 3 and to be engaged beneath the side flanges 26 thereof. The main body of the spacing members are formed as resilient strips '55 for yieldingly engaging the inner face of the guide channels formed in the window frame. The projections 74 and T5 are recessed to receive the supporting strips l6 and their attachment devices. The end 15 may conveniently be secured in the assembled window support by forming a slotted extension 18 thereon for receiving an anchoring link 19, anchored respectively to the spacing member 26 and housing 60 of the checking devices 24.

It will be seen that two assemblies of checking devices and spacing'elements are provided, one set above and the other below the hinging assembly, for assuring uniform operation thereof.

Since the window-checking devices 24 normally require some slight movement of the window before they become fully effective, means are provided for locking the upper window 4 independently in its uppermost position. This may comprise a snap spring device 80 secured to the housing 60 of the checking device 24 and formed with a projecting end 82 engaging against and above the control strip H or its mounting bracket l8 when the window is in its uppermost position.

The supporting members 8 may be weatherstripped with respect to the window frame and guide channels thereof, if preferred. As shown in Fig. 4, the supporting members 8 are formed completely of metal. the side flanges of these members there are formed outwardly extending projections 84, in position to engage against corresponding shoulders 85 on the parting strip and molding formed at the sides of the channels. parting strip and molding are formed with grooves 83 of sufiicient width that the supporting members 8 can be moved outwardly or inwardly to the extent of their normal movement when the window is tilted. This is illustrated in Figs. 4 and 5, showing the supporting member in its normal position, with the window vertical (Fig. i), and in its extended position, with the window tilted (Fig. 5).

The weather-stripping effect of the projections 84 and 86 can be increased, if desired, by placing a thin strip of metal over the exposed face of the parting strip, as shown in Fig. 5b, the metal facing 90 being formed of springy 7 material and having edges 92 engaging against the sides of the supporting member 8 or the ribs 84, if em ployed.

A modified form of weather stripping is shown in Fig. 14. In this form the metal strip 94 is permanently mounted in the base of the window channel and may include both the side projections 96 and intermediate projecting ribs 98, the

former engaging substantially against the outer face of the supporting member and the latter extending into the interior of the supporting members for engagement with the flange on the inner face of the supporting members 8. It will be understood that in this construction the housing 60 of the checking devices will be formed with corresponding grooves 99 (Fig. 13) for accommodating the intermediate projections 98. It will also be understood that the checking devices herein disclosed could be omitted and counter weights or springs utilized instead. The checking devices are particularly adaptable to the present construction, however, since they can be made to coact with the same control bar as the locking devices.

From the above description it will be seen that the devices can be assembled by sliding the housing for the checking devices and the end spacing elements into the ends of the channel constituting the supporting members, these elements being anchored to the hinging devices by'the straps, as shown. Attachment of the hinge pin Near the outer edges of As shown, the

in place then secures all of these parts against longitudinal movement.

In the operation of the window it can be moved upwardly and downwardly in the manner of a double hung window. For washing purposes or for ventilation or repair, the window can be moved away from closed position and then rotated on a horizontal axis to any desired position. When the window has been moved out of vertical position, the locking devices serve to prevent any upward or downward movement of the supporting members, so that the window cannot fall out of its frame. Movement of the window to its vertical position again moves the locking devices to inoperative position. Upward movement of the window is substantially unobstructed, but in downward movement thereof the checking devices are brought into operation-and bear the weight of the window. Since all of the checking and locking devices operate in connection with the identical locking bars in the window frame, which locking bars are guided with respect to the window supports, all of these parts must necessarily remain in position for uniform and unfailing operation.

The window herein disclosed is readily moved upwardly or downwardly in the frame, due mainly to the employment of the resilient mem- These members have several They accommodate the movement of the side supporting members 8 when the window or sash is tilted away from vertical position. In addition they center the window in the frame, make up for any variation in the width of the window or frame, prevent binding in case the wood should swell, and finally they serve as skids or anti-friction supports during movement of the window.
